DAVID GUELBAUM, OF SYRACUSE, NW YORK,

CLOSED ADJUSTABLE LIGHTING B' U'R1E2II,.

Application filed February 4,1921. serial No. 442,432. Y

To all lcf/7mm t may concern:

Be it known that I, DAvrD GUELBAUM, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Closed Adjustable Lighting'Burner, of which the following is a specification.

This invention of a closed adjustable lighting burner, in its main feature of confining the gas jet and mantle ywithin a closed housing, is similar to my patent application filed Jan. 24, 1921,.Ser. No. 439,453, and has likewise for its object efiiciency in the use of gas for lighting, as regards:

l. The quantity of gas consumed;

2. The quality of `light obtained, and

3. The durability and strength of the inl 'candescent materials used.V

But this application differs Afrom said pending applicationin the, following features:

1. In place of the eXact proportioning of gas and air by means of the mixing and proportioning valve, especially invented for such purposes, the proportioning of gas and Vair is here done approximately only, but in a simpler and cheaper way, by direct regulation of the air supply tothe gas` jet, prior to its entrance intothe incandescent mantle.

2. In place of the usual small gas jet in the center of the incandescent mantle, the gas jet is here transformed into a cylindrical sheet stream of adjustablelthickness, close to and concentric with the surrounding incandescent mantle, whereby lthe gas and air become thoroughly Vintermingled, and the Vwhole heat developed 'is evenly transmitted to the mantle.

My present invention comprises the above set vforth novel features, embodied in the combinations and constructions hereinafter set forth and described.

Iii-'describing this invention reference is had -to the accompanying'r drawings, in which like characters designate the same corresponding yparts in` all the views.

Fig. 1 is aV sectional elevation of my closed adjustable lighting burner with the annular gas and air passage into the mantle shown closed.

Fig. 2 is a similar sectional view with said Vgas and airY passage shown fully open.

Figs. 3, 4 and 5 are horizontal sections of same on the lines 3 3, 4-4 and 5-5 respectively of Fig. 1. v

Figs. 6, 7, 8, and 9 arev details of'various parts.

The burner consists of the regulating fitting 1, Fig. 1,having two inclined slots 1n diametrically opposite eachother, Yas shown in development on Fig. 6. Thisfitting is supported by the bushing 2, slidingly fitted into same,vby means ofthe lbolt 3, which passes through` the bushing and the two inclined slots on said regulating fitting, and also through the ring 4,v Figs. 1,

2 and 4, provided with the radial arms 5 serving to support a shade or reflector .of any style (not shown), if sodesired.

The bolt 3 is provided with the two square locking washers 6 and 7 and the thumb nut 8, Figs. l and 4. The four edges of the washer 6 are bent'up,.as shown on Fig. 9: two opposite edges are bent over the ring V4, butting against the regulating fitting 1,

but without pressing on the ring4, a slight clearance being left between Lwasher and ring, as shown on thedrawing; this-pre Vvents the washer' 6 from turning. The other .two opposite edges of the washer 6 are bent up -against the surfacesv of the square head of the bolt 3, thus preventing'the bolt 3 from turning.

The edges of the washer 7 are likewise bent over the ring 4, butting against the regi ulating fitting 1 without. pressing on .thering 4, a slight clearancebeing left between washer and-ring, ask shown on drawing, Fig. 8.

Therefore, when thev thumbnut .8. is tightened up, the two washers l6 and 7 will press on the regulating fitting 1, fastening itv immovably to the bushing 2'; while, when.

loosening slightly the thumb nutS, the regu` lating fitting can be -turned one way or'the' other, thel bolt 3 slidingin vthe inclinedy slots 1'L1 shown on Fig. 6, thereby raising or-'lowering the regulating fitting 1 relativeto the bushing 2. Thehandle 9, sprung into position, as shown in ysection Fig. 3, serves asa grip for turning the regulating fitting.v

In its upper part the regulating fitting is provided with ai'r openings, vshown in de.

Vvvelo ment on Fie. 6. VThese o eninvsare c overed over by the ring 10, Fi 1, having,`

similar openings, as shown in evelopment Fig. 5. By turning thefring lO't-he airk inlet.; openings can Vbe closed or opened as much as desired. On Figs. 5, 6 and7 these air: inlets are shown halfopen.

At'gits top',` the regulating fitting 1 termi nates into a fiange carrying the tile seat 12 having a projecting hub in the centre lforVA supporting amantle and which can thus be VVraisedgorlloiveredtogether with the regulatin fitting, as `previously explained.

in the center ofthe burner there is a stationary tile piece 18 with the tile pipe 14, carried on top of the metalcross piece 15,

'itted'securelyin the bushing l2 and supported byjthe bolt 3, `asshown on Figs. 1 and 2 and in section on Fig. 4. Thesetwo tile pieces, 12 and 13,'conform to eachother in their contour, forming an annular passage between them, which can be closed or opened as much as desired by raising orloivering the regulating fitting 1 'with its tile seat V12, While. the tile piece 13 relmains stationary on top of the bushing 2.

On Fig. 1 this annular passage is shown closed, While/on Fig. 2itis shown near fullyl open. Y

Thejincandescentmantle Y16 mayv be carried either by thfe'movabletile 12,V as shown on Fig.gl1, .1n case .it/has resistance enough Y against'. collapsing; or itmay be suspended as. shown on'v Fig-2.

j ThebushingQ -istapped at the bottom, as, shown on ..Fig.'1, and t'ogether'ivithY the regulatingfitting 1' may be readily Screwed on with outside air, as hereinafter described.

The. globe isclosed at its bottom by the i flange ofthe regulating fitting 1 and its tile seat'12..` Through the air openings in the upper part of;the regulatingfitting` 1, con-V trolled by theair-shutter ring 10,the air is admitted into the annular passage between they two tilevseats V12an`d 13, 'together with the gas flowing through. the bushing 2, and, intermingled with eachother, pass into the interior space lWithin theV gas mantle 16,`

' around the tile pipe `14.

."Th'e combustion gases 'formed'by the burn-V ing of the gas within the mantle will'fill Vup ,the globe andy pass out into the atmosphere i' through the top of theglobe, Whose topV openingis just"4 sufficient to let these. combustion gases out, butV is not Wide enough to let air Thus, the mantle is` surrounded'by the frointhe top nof the stationary tile'pipe 14 asA and for the purpose described.

he regulating l.fittingV 1 I formed bythe globe a minimum amount of free air, but only non-oxidizing combustionY gases, in which metal fabric does not deteriorate, and, therefore such metal fabric may be used for the incandescent mantle inside that housing, as a material safe to handie and l commen incandescent mantie may be used.
